J fMy'invention relates to aslicing machine and 1s applicable for example to a shcing machine of a type having a rotary and pref erably a motor driven knife. One object of my invention is to provide means for clearing the slices from the knife as they are seV Lered. fAnothe'r object is to provide the support for the front end of the work and for the-sliceas it is severed." Another object is -fa to insure the delivery of flat and uncurled slices; Another object'is the provisionof means for'the retu'rnof the work carrying carriage employed for conveying the work past thecutting edge of the knife. Another is object is to providemeans for protecting or shielding theknifeedge. Otherobjects will appear from time to time in the course'of the specification and claims. r a

Figure? Figure 9 is a partialendf elevation of the structure shownin Figure 7. Like parts are indicated by like symbols throughout thespecification and drawings. A generally} indicates a base upon which is mounted-the motor A with its shaft A and pulley A and driving belt A B indicates a'guardplate lying in a generallyvertical plane andB a gauge plate, details of guard and gauge plate'forming of themselves no part of the present invention.

' B is a rearwardly extending guard member overlying the rear face of the knife below described. B indicates a carrier member for thegauge plate which may be actuated in any suitable manner, for example by rotation of the knob 13*, the particular driving con nection employed being not illustrated as forming no part of the present invention. The edge of the gauge plate adjacent the knife edge is sharp or squared as at B in order to provide as adequate and complete a shield or protection for the knife edge asis possible, when the gauge plate 13 is moved to its inoperative or forward position as shown in Figure 2.

r C indicates a knife mounted upon any suitable knife shaft carrying the pulley C Wherebyit may be driven by the belt A. V

D indicates a track'and D a guide track therebeneath, herein shown as of rectangular cross-section. The tracks are parallel and both are upwardly inclined from'the left to the right of the machine as shown in Figures 1 and 2. Mounted for movement along the track D is the meat carriage gen erally indicated as D which includes a generally horizontal or slightly inclined portion D uponwhich the work to be sliced rests.

Associated: with and depending from'the member D is the track engaging portion D. with the lower extension D for engagement with A the guide track D D indicates a flange or upturned portion across the edge or end of the carriage portion D which is farthest from the knife when the carriage is in withdrawn position as shown in Figures 1 and 2. The portion D has associated with it an upward projection D lying adjacent the face of the gauge plate. It will be realized that the proportion and position of parts is such that the edge D 'of the carriage is parallel with and rather closely adjacent tothe faceof the guard plate and to the guage plate when the gauge plate is in A knife edge, as shown in Figures 4 and 5, and closely approaches it.

tends forwardly of the cutting plane of the knife edge. This portion E is arcuately formed to conform to the cnrvatureof the knifeedge and closely approachesit.

. It will be observed as from Figures 3 and gthat the strip or support E inpart underlies the au e late B and its carrier B D b p 'Thus the member E exercises its supporting function regardless of the position of gauge plate and the gauge plate moves freely ticle to be sliced which lies closelyadj'acent' the cutting edge ofthe knife and further assures'afclean cut to the Very end of the slice.

The top of the member E preferably lies in the same plane'as the topof the meat support member D with the, edge D? of the inclined portion D closely approaching the member E4 Mounted for movement on the carriage D? is ariysuitable pusher plateG attached to Whichfis ahandle portion G extending to thejb'ea'ring sleeve "G 'whi'chfslides on the pin'ortrack G A lower guiding pin: G is provided which. is engaged by the arm G? downwardly extending from the sleeve G and formed asat'G ItO engageitheipineG and prevent rot'atijonof the sleeve G The 7 member G or the sleeve G are equally avail; able for use asa handle for the manual actuation of the carriage.- When the pusher plate'is removed'then the pin G forms effective handle.

Referring to thevariantforms of Fig nres6 to 9,'adjacentlthe path of movement of; the carriage at theedgeofjthe cutting. arc

of the-knife is positioned a supporting member L whichismou nted on the frame of; the slicing machine. It includes a portion; L

" which projects forwardly of the edge of the knife andtenninates closely adjacent theiopposedvv edgeK of the carriage. The member L isheld in place for examplev by the screws L and the edge of the portion rL 'is' positioned or initially set'to reduce to a minimum the space between it and the edge K. The portion L? of the block or support extends to the rear of the knife andisprovided with a face L conforming to the contour of the knife. It will he observed as in Figure -9 that the main portion ofthe top of the mem;

In effect the knife. edge is positioned in a recess or cut away portion E and the form of this cut away portion is such that at E the support exber L lies in the same plane as the'top of the meat support member D It is however, provided with a rounded plane of the top of the member li with a minimum of friction and deformation.

- The knife edgef-is-positioned in a recess or cut-away portion L inthe snpportmg member L, si1n1lar to the cut away'p'ortmn "E of the work support E previously described. y
